Painting in Perspective

Shake allows you to paint in perspective using a Transform CornerPin function in conjunction with QuickPaint.

1.

Start by clicking the New Canvas icon.

2.

Click the Paint brush icon to enter Paint mode.

3.

Select FileIn from the Image tab and go to the Lesson06 folder.

4.

FileIn the wall.0001.tif clip and fit the image to the Viewer by pressing the F key.

5.

Highlight QuickPaint1 and select a CornerPin node from the Transform tab followed by an Over node from the Layer tab.

CornerPin pushes the four corners of an image into four different positions.

6.

Connect the output of the wall node to the right input of the Over1 node.

Your tree should look like this:

7.

Click the right side of the CornerPin1 node to edit its parameters.

8.

Adjust the four corners of the CornerPin so that they match the corners of the building.

The top-right corner of the building isn’t visible, so you’ll have to zoom out in the Viewer with the minus sign (–) and pull its upper-right corner above the upper-right corner of the image. You can use the center line to judge the accuracy of your placement.

9.

Click the right side of QuickPaint1 to edit its parameters.

10.

Make sure that you are in Paint mode and that the Frame mode toggle is on.

Frame mode paints only on the current frame.

11.

Press the P key to pick color from the wall, and proceed to paint graffiti.

12.

Feel free to change the size of the brush as needed in the Paint Controls subtab.

You may have noticed that the profile of your brush has changed and is now a vertical oval. The strokes that you are painting are in perspective with the wall. How about giving the Clone brush a try?

13.

Disconnect the wall clip from the tree and attach it to the left input of a new QuickPaint node.

14.

Double-click the QuickPaint1 node so that you can view and edit it.

15.

Select the Clone brush.

The Clone brush will copy from whatever is created by the paint node or whatever comes from the first image input. Shift-drag to move the brush target relative to the source.

16.

Shift-drag to offset your paint source.

17.

Clone various parts of the image using different brush offsets.

18.

While you’re at it, experiment with the Smudge brush.

19.

Make sure that the Smudge brush is set to the Hard setting when you use it.
